Embodiment 1

[0021] Example 1 This method was carried out in Tengzhou, Shandong on November 22, 2011.

[0022] (1) Selection of yam cubes: select yams harvested in Anhui this year, selection criteria: mature, pest-free, and mechanically damaged yam cubes. Under well-ventilated conditions, keep the temperature at 15-25°C and let it dry naturally for 1-2 days for later use.

[0023] (2) Pretreatment: Put the spare potato pieces into the cold storage for storage; first arrange wooden strips with a height of 8-15cm on the floor of the cold storage, and then place the French fries neatly and horizontally on the wooden strips and fix them with wooden frames around the French fries; The height of the cold storage depends on the height of the cold storage and the convenience of manual operation; the cold storage conditions are: temperature control 5-6 ℃, from November 22 to January 31, 2012.

[0024] (3) Post-processing: take the French fries out of the cold storage, and dry them outdoors in a ve...

Embodiment 2

[0029] Example 2 This method was implemented in Zhanjiang, Guangdong on February 1, 2013.

[0030] (1) Selection of potato pieces: choose yam potato pieces harvested at the end of October in a county in Huainan City, Anhui Province as seed potatoes, select mature yam potato pieces that are free from pests and diseases, and without mechanical damage, and keep the temperature at 15- 25°C, dry naturally for 2-3 days, set aside.

[0031] (2) Pretreatment: Put the spare potato pieces into the cold storage for storage; first arrange wooden strips with a height of 8-15cm on the floor of the cold storage, and then place the French fries neatly and horizontally on the wooden strips and fix them with wooden frames around the French fries; The height of the cold storage depends on the height of the cold storage and the convenience of manual operation; the cold storage conditions are: temperature control 5-7°C, cold storage until April 3, and the planned sowing time is April 12.

Abstract

The invention discloses a regular dormancy breaking method for dioscorea opposita thunb seed tuber. The regular dormancy breaking method comprises: naturally drying mature, pest-free and damage-free dioscorea opposita thunb tuber blocks in the sun, placing into a warehouse, and storing, wherein the cold storage time is determined according to a seeding time; and 7-10 days before seeding, taking out the dioscorea opposita thunb tuber blocks, carrying out outdoor air drying, cutting into segments according to the requirement, carrying out disinfection treatment with an agent, inducting germination with a chemical agent, placing in a sand pile and carrying out germination, or carrying out direct seeding germination, and achieving germination seedling emergence after 15-20 days. According to the present invention, with the method, the regular dormancy breaking can be achieved according to the planting time schedule, the dormancy breaking germination rate can achieve more than 90%, the seedling emergence rate is more than 85%, the planting season and the harvesting marketing time can be adjusted, and the economic benefits can be improved; and the seed source problem of the dioscorea opposita thunb in the southern China can be solved so as to seed in the winter while harvest in the summer, the early seeding seedling emergence in the northern region can be achieved, the effective growth period can be increased, and the yield and the quality can be improved.

Description

technical field [0001] The invention relates to the technical field of Chinese yam seed potato, in particular to a method for breaking sleep at regular intervals of Chinese yam seed potato. Background technique [0002] Chinese yam (Dioscorea opposita Thunb.) is also known as Chinese yam, Chinese yam, native potato, yam, sweet potato, and Yuyan. It is the dry rhizome of yam yam. Huaishan is rich in nutrition and has a good therapeutic effect. In recent years, people have paid more and more attention to nutrition and health, and Chinese yam has also been sought after by people. The demand for yam began to exceed supply, and the price gradually increased. Therefore, how to scientifically plant Chinese yam is a topic worth studying. [0003] Yam seed potatoes are dormant. Generally, they are harvested in October-November of the current year and can only germinate in March of the next year. The dormancy period lasts for 4-5 months. are strictly restricted. Therefore, if "Y...
